Thomas had placed a towel on the kitchen table. Never one to resist temptation, Rocky climbed up immediately to nest. Max also flew over to do some nesting of her own. She never initiates this -- she only comes over when Rocky's already nesting. You kind of have to look closely to see Rocky:As long as she stays a few inches from him, Rocky seems fine to have them both lifting the towel up and then slam it on the ground.
Some newspaper was destroyed during nesting:
I don't think that Max realizes any nesting urges from this -- it appears to just be a game.
